These maps determined that both parties travel a similar distance to voting booths, but republican party members on average traveled a bit further. However, the next question that this study asks is why? Why go to a different area to cast your vote when there is a booth in your own neighborhood?

This information yielded that "partisans relocate based on destination characteristics such as racial composition, income, and population density but additionally prefer to relocate in areas populated with copartisans."
